Though Garner seems to be pretty much perfect at everything, at Monday night's Alexander and the Terrible, Horrible, No Good, Very Bad Day premiere in Hollywood, Calif., the actress suffered a wardrobe malfunction when she revealed a pair of nude Spanx under her LBD.
Looking great in an elegant Valentino number, the red carpet mishap happened when her dress flew open while she was posing next to co-star Steve Carell.
But Garner, 42, didn't let the moment get her down, still looking great in a pair of black Jimmy Choo ankle-strap heels and accessorizing with a sparkly Oscar de la Renta bag.
"I'm in New Balance sneakers every day. I try not to be because I get made fun of by my husband and friends, but it’s not natural for me to think about how I look on a daily basis," the mother of three told Allure in June about her fashion sense. "I'm not someone who should be in a beauty spotlight. I was one of those people who wore pajamas to class every day in college, and I would still be that way if I could! ... I'm kind of my own walking beauty disaster."
